Laravel如何配置数据库表前缀

例如：表前缀为“prefix”,用户表全名为“prefix_users”。
则进入项目文件夹“config”->“database.php”内：

'connections' => [

        'sqlite' => [
            'driver' => 'sqlite',
            'database' => env('DB_DATABASE', database_path('database.sqlite')),
            'prefix' => '',
        ],

        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'strict' => true,
            'engine' => null,
        ],
.......以下省略

找到这一行：

 'prefix' => '',

将其改为：

'prefix' => env('DB_PREFIX', ''),

在进入项目根目录下的".env"文件中,找到这一区块，在其下方添加DB_PREFIX=prefix_ 即可

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=demo
DB_USERNAME=root
DB_PASSWORD=root
DB_PREFIX=prefix_
